To all whom it'mag/ concern.'

Be it known that LSALvADoR DOMINGUEZ, a `'citizen of Mexico, @residing at San tonio, in the county-of Bexar 4and State of Texas, have Einvented Vnew fand yuseful Power-Multiplying Mechanism, of which itheyfollow-ing is a specification.

The object of the ,invention isto .prov-idea .comparatively .simple mechanism for imultiplying lt'he #eiiicient ..power of a .prime mover of any of the well known types adapted .to use as a motive agent steam, .lg-as, AAelectrlclty,

etc., and -designed to conserve and Vutilize kinetic energy and apply momentum with the utmost economy lin order to attain the result sought. y y

With these and other objects in view, which will bedeveloped in the cou-rseofithe following description, the invention consists in a certain construction, combination land relation of .parts hereinafter specifically set forth -and it will be understood .that changes in the form, .proportions and -minor details of construction may -be :resorted to within 'the scope ofthe claims, without departing embodying a base or supportand coperating with the motor, andtransmission mechanism by which' the Lpower is conveyed jto the driven elementJ 'from Ywhich it may be taken to perform 'the desired work.

In the illustrated embodiment of the .invention Athe motor which Ain this 4instance consistsof Aa shuttle vor reciprocatonv member embodiesa frame having-terminal.trucks -10-suitably'connected asby bars llandhaving bearing wheels 12, which .may beofthe flanged type as shown to traverse tracks .supported by Ythe base,4 said bear-ing` rWheels ybeing `fsecured to spindles 14 :operating in bearing .boxes 15 at Athe opposite sides of each truck. The motor also includes a prime mover 16 which vmay be lof any of `the well jknowfn Atypes and is shown Ias'being carried by the Vconnecting bars 11 Vbetween the trucks, :isn common with weights '-17 which .may be suitably arranged thereon 'to secure .the maximum eficiency in -obtaining the desired :traction and operating i-eliect, as will appear hereinafter. .Secured to the spindles 14 yor .to the xbearing Wheels, l2 are driving ,gears 18, traversing andy coperating with racks V19, also permanently secured Ato .and supportedthebase or stator, whereby as .the motor frame Vis reciprocated, said :gears lin .traversing .the racks .impart rotary move- .ment to v.the spindles. .Driving wheels are also .mounted upon 'the trucks, two ifor each truck being yillustratedin ythe drawings and lbeing `indicated at 20, Veach driving wheel having .a sleeve shaft 21 fitted Vupon Vthe spindle 14 4and .carrying a rpulley 22 which is connected .by a `belt or similar means 23 sto Va driving pulley ,24 .of .the Aprime mover., the belts running to one truck being `crossed soasto limparttothedriving wheels at op- .posite ends fof vfthe motor `motion in #opposite directions, that is, from the top Vdownward .toward Athe .prime mover. These driving wheels contact peripheraflly with traction .surfaces 25 also secured 4permanently in the .base `or stator and consisting in fthe con- Vstruction illustrated of 'horizontal bars .which v.are V.preferably superfcially ycorrufgated or .roughened-'to insure the proper ad- Vancei ofthe motor inione direction or the lother by .thecontact of said driving wheels with the .traction surfaces. 7

.It Willbe noted that withsthe construction as so yfar ydes,cribed,pthe operation of the driving wheels is continuous, .the set at one end of the .motor yturning in the opposite direction Vfrom the set atftheother end, and these driving 'wheels or sets Aof `driving wheels are designed to contact ,with their yrespective 'traction surfaces, alternately. To4 :accomplish this, .one half of the pefriphenyoffeach driving wheelisreduced or cutaway, so ,that throughout one .half of the :periphery .of fthel vwheel the ,latter fis radial-Ly [reduced as shown .at f26. l`When the driving wheels of one truck are in contact with their traction surfaces, the driving wheels of the other truck are f. out of` Y direction to the limit of its path and then the motion of the frame will be reversed byV the action of the driving wheels of the other truck. lt Vwill be observed that the gears 18 with their bearing rollers or wheels are. mounted as hereinbefore described to turn independently of the driving wheels.

In order -to guard against injury to the base or stationary portion of the mechanism, and at the same time to utilize the rebound and momentum incident thereto, the trucks are provided at their outer extremities with buffer plates or members 27 supported by suitable Vbuffer springs 28 held in place by rods 29, and the ends of the base or stationary frame are provided with corresponding buffer plates 30 yieldingly held in their normal positions by springs 8l and suitable rods 82. Y

A driven shaft 33 is'suitably mounted in the stationary frame to'actuate a belt pulley 34 or any other suitable driven member, and

associated. with this driven shaft it has been found expedient to employ main and auxiliary i'iy wheels 85 and 36 either or both of which may be thrown into engagement with the shaft, clutches 37, independently operable by levers 38 and 39 being employed for this purpose. In starting the engine it is desirable to throw in the auxiliary. fly wheel and afterward the main wheel may be coupled, and in stopping the reverse procedure should be followed, after which the prime mover may be stopped.

Having now described the motor and the means by which it is caused to reciprocate regularly throughout the length of the tracks or bearings provided for it, reference is made to the transmission mechanism by which motion is communicated Yfrom the motor to the. driven shaft or element and which consists essentially of a rocker having a suitable spindle 41 mounted in bearing boxes 42 and rocker actuators'43which cooperate with shoes 44 on the rocker, said rocker actuators being carriedv yby the spindles 14 and hence receiving motion fromvthe gears 18 as they traverse the racks 19. Inasmuch as the rocker has an oscillatory movement while the path of the gear and 'of the motor frame is rectilinear, the bearing face of the shoe 44 and the contacting face of the rocherV actuator have been developed upon .kinematic lines, the latter being spiral as shown in detail in Fig.I 5, and the former being an approximation to an ogee curve. These relative forms have been found eecadvances from the position shown in Fig. 2,

the rocker actuator at the forward end of the truck frame will contact gradually with the surface of the shoe o-n the rocker-.and will avoid unnecessary friction. During this movement of the parts, the driving wheels at the rear of the motor frame are in contact with their traction surfaces, while the driving wheels at the forward end of the frame are out of contact with their traction surfaces. versed when the motor frame has reached the limit of its movement in the direction indicated and whereupon the direction of movement is reversed to cause a reverse tilting movement of the rocher. l

Carried by the driven shaft 83 are gears Ubviously this order is re-Y 45, one or more of which may be used, and Y meshing therewith are gears 46, which. stand continuously in a common direction and therefore impart a continuous rotary motion to the gears 45 and hence to the driven shaft. Such motion is communicated thereto through the crank shafts 47, which in turn are connected with the rocher 40, through the medium of the levers 48 and the pitmen 49 and 50, both of which are adjustable as to length by mea-ns of `turnbuckles or other equivalents.

From the foregoing description it will be understood that the moto-r consisting of the reciprocatory frame receives its motion from the prime` mov-er, the energy of 'which is communicated through the belts and pulleys to the driving wheels located at opposite ends of the motor frame and constructed and mounted to operate alternately, and that during these movements in opposite directions the gears 18 traversing the racks 19 serve to actuate the rocker actuators which alternately act upon the shoes of the rocker Vto cause an oscillatory movement thereof,
